“…CS/rGO has also been combined with Fe 3 O 4 to give magnetic CS/rGO adsorbents and employed to give the effective adsorption of an antibiotic [ 186 ] and dyes [ 187 ]. While the conducting rGO can be beneficial in depositing well dispersed metal/metal oxide particles through reduction, there is evidence to show that CS/GO composites have a higher adsorption capacity when compared with the reduced GO counterparts.…”

The quality of water is continuously under threat as increasing concentrations of pollutants escape into the aquatic environment. However, these issues can be alleviated by adsorbing pollutants onto adsorbents. Chitosan and its composites are attracting considerable interest as environmentally acceptable adsorbents and have the potential to remove many of these contaminants. In this review the development of chitosan-based adsorbents is described and discussed. Following a short introduction to the extraction of chitin from seafood wastes, followed by its conversion to chitosan, the properties of chitosan are described. Then, the emerging chitosan/carbon-based materials, including magnetic chitosan and chitosan combined with graphene oxide, carbon nanotubes, biochar, and activated carbon and also chitosan-silica composites are introduced. The applications of these materials in the removal of various heavy metal ions, including Cr(VI), Pb(II), Cd(II), Cu(II), and different cationic and anionic dyes, phenol and other organic molecules, such as antibiotics, are reviewed, compared and discussed. Adsorption isotherms and adsorption kinetics are then highlighted and followed by details on the mechanisms of adsorption and the role of the chitosan and the carbon or silica supports. Based on the reviewed papers, it is clear, that while some challenges remain, chitosan-based materials are emerging as promising adsorbents.

“…GA can be applied to various optimization problems because of its adaptability, at the same time, it can be used to search the entire solution space to obtain the optimal condition. 33 The optimization efficiency and results are not affected by the initial structure, and the crossover and mutation operations avoid the GA from falling into local extrema. In this study, the initial population was 50 individuals, which were created by the uniform creation function and Then low tness chromosomes were eliminated, and the rest were subjected to select, cross and mutate until a suitable result is obtained.…”

“…Though relatively novel, there are already such intelligent magnetic materials which have been examined for their adsorption performance in water and wastewater remediation (Yu et al 2020 ; Ciğeroğlu et al 2021 ; Leonel et al 2021 ; Yang et al 2021 ). Therefore, we think it is opportune to borrow insights from these repositories of scientific data to design and scale-up intelligent magnetic nanoadsorbents-based adsorption units for application in full-scale water purification and wastewater treatment systems.…”

Pure water will become a golden resource in the context of the rising pollution, climate change and the recycling economy, calling for advanced purification methods such as the use of nanostructured adsorbents. However, coming up with an ideal nanoadsorbent for micropollutant removal is a real challenge because nanoadsorbents, which demonstrate very good performances at laboratory scale, do not necessarily have suitable properties in in full-scale water purification and wastewater treatment systems. Here, magnetic nanoadsorbents appear promising because they can be easily separated from the slurry phase into a denser sludge phase by applying a magnetic field. Yet, there are only few examples of large-scale use of magnetic adsorbents for water purification and wastewater treatment. Here, we review magnetic nanoadsorbents for the removal of micropollutants, and we explain the integration of magnetic separation in the existing treatment plants. We found that the use of magnetic nanoadsorbents is an effective option in water treatment, but lacks maturity in full-scale water treatment facilities. The concentrations of magnetic nanoadsorbents in final effluents can be controlled by using magnetic separation, thus minimizing the ecotoxicicological impact. Academia and the water industry should better collaborate to integrate magnetic separation in full-scale water purification and wastewater treatment plants.
